Title: Valve actuator
Inventor: CAMPBELL ROY SIDNEY
IPC: F16K31/163
Filed: 1985-11-15
Abstract: In a fluid-controlling valve having a movable valve member and an actuating mechanism comprising a rotatable worm and nut mounted for axial movement along the worm, either said worm or said nut is operatively connected to said movable valve member so that an input movement to the other of the aforesaid components (i.e. the nut or the worm) will result in a desired output movement of the valve member. In one embodiment rotation of a worm 16 by means of a handle 17a results in 90 DEG  rotation of a fork 19 attached to a nut 17 so as to actuate a butterfly disc (12 Figs. 1,2). In a second embodiment and nut (27 Fig. 4) forms a piston which is reciprocated in a cylinder (25) by fluid pressure so as to rotate a worm formed on a shaft (24) and thereby actuate a multi-turn valve spindle (26). <IMAGE>

Title: Metering pump
Inventor: MORLAND ALBERT HENRY
IPC: B01F15/04
Filed: 1986-03-14
Abstract: A pump is provided which is capable of delivering measured doses of a liquid. The pump has a body 1 having a longitudinal passage 2, and a pair of opposed pistons 3, 4 slidingly received in the longitudinal passage. Cross passages 14, 13 in body 2 communicate with the longitudinal passage and constitute respectively an inlet port and an outlet port.

Patent GB-2177272-A (GB)
Title: Reversing electric motors
Inventor: GUZEK WILLIAM KENNETH
IPC: H02P6/00
Filed: 1986-08-12
Abstract: The forward/reverse logic responds to a controlled reduction of the supply due to a speed control so that upon reduction to a set value, below a threshold corresponding to the stalled motor condition, the logic causes the direction of rotation to reverse. For an electronically commutated motor, when the speed control input (P 14) falls below a threshold (VREF9), a bistable arrangement (D13, D14) changes state so as to invert the counting sequence of the control circuit and reverse the motor which will recommence rotation in that direction upon increase of the speed control beyond the stall position. The device may be used in a control for a ceiling fan. <IMAGE>

Title: Releasable connection for a well diverter assembly to a flow line
Inventor: REYNOLDS GRAEME E
IPC: E21B21/01
Filed: 1987-01-27
Abstract: A flow line connector and seal apparatus for plain end tubing is provided on a transfer tube assembly (A) pivotally mounted to a mud flow line to allow connection of the mud flow line (F) to a well diverter assembly (D). The connector and seal (20) is oriented concentric with an end of transfer tube (12) and is moved along the longitudinal axis of the transfer tube by a turnbuckle. The connector is then sealed to the transfer tube and to a plain end fitting on the diverter assembly by compression of deformable seals sandwiched between rigid antiextrusion rings. The radius of the connector/seal assembly is such that connection of the transfer tube assembly and diverter assembly fitting is possible even when minor misalignment exists. The orientation of deformable seals between anti-extrusion rings allows for a high pressure seal while protecting the deformable seals during connection and disconnection operations. <IMAGE>
